Tuberculosis (TB) is a communicable disease caused by the bacterium Mycobacterium tuberculosis (MTB) and is a persistent problem in the developing countries. Loop-mediated isothermal amplification (LAMP) allows DNA to be amplified rapidly at a constant temperature. Here, a LAMP method was combined with a chromatographic lateral-flow dipstick (LFD) to detect(More)
The aim of this study was to characterize the organic solvent and detergent tolerant properties of recombinant lipase isolated from thermotolerant Bacillus sp. RN2 (Lip-SBRN2). The isolation of the lipase-coding gene was achieved by the use of inverse and direct PCR. The complete DNA sequencing of the gene revealed that the lip-SBRN2 gene contains 576(More)
The best-known acetone-butanol (solvent)-producing bacterium is the Weizmann organism, Clostridium acetobutylicum, which was used for starch-based industrial fermentation. In the past two decades, cultures of "C. acetobutylicum" from various culture collections have included organisms that were isolated for sugar (molasses)-based industrial solvent(More)
Piezoelectric DNA-based biosensor technology was developed as a new method for detection of M. tuberculosis. This method consists of immobilizing a thiol-modified oligonucleotide probe on the gold electrode surface of a quartz crystal, using a self-assembled monolayer method. The advantage of this study is that a non-amplified genomic bacterial DNA target(More)
The bacterial strain TD1 was isolated from Tao Dam hot spring in Thailand. Strain TD1 was Gram positive, rod-shaped, aerobic, motile, and endospore forming. The cell was 2.0-40 μm in length and about 0.4 μm in diameter. The optimum growth occurred at 55-60 °C and at pH 7-8. Strain TD1 was able to grow on medium containing up to 10% NaCl. The DNA G+C content(More)
OBJECTIVE To determine comparative in vitro activity of sitafloxacin against clinical isolates of bacteria from Thai patients with urinary tract infection and those with lower respiratory tract infection. MATERIAL AND METHOD 1,255 clinical isolates of Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa, Acinetobacter(More)
Tuberculosis, a major health problem in developing countries, has re-emerged in recent years in many countries. While it is accepted that various lymphocyte subsets are important responses to mycobacterial infection, the roles of NK and NKT cells in producing cytokines are still unclear. Thus we have evaluated, in Mycobacterium tuberculosis infection, the(More)
Conversion of Campylobacter upsaliensis to the coccoid form during aerobic incubation at 37 degrees C was not prevented by treatment with chloramphenicol and was accompanied by severe decreases in isocitrate dehydrogenase activity and oxygen uptake. Although the coccoid forms fluoresced orange-red by acridine orange staining, agarose gel electrophoresis(More)
OBJECTIVE To evaluate hemoglobin E screening tests in a large scale of cases. MATERIAL AND METHOD A cross-sectional descriptive study was conducted Whole blood obtained from subjects was evaluated for CBC, OF, DCIP, and hemoglobin typing. RESULTS Five hundred twenty seven hemoglobin E and 280 reference subjects participated. DCIP's sensitivity,(More)
The modified GC medium (MGC) was developed for identification of beta-hemolytic group B streptococci. This medium was developed on the basis of enhancing-pigment production of group B streptococci. Three hundred and thirty isolates were tested including 180 isolates of beta-hemolytic group B streptococci, 102 isolates of beta-hemolytic non-group B(More)
